Troubleshooting Tips For Pleated Air Filters

Common troubleshooting tips for pleated air filters include checking for clogged and dirty filters, reduced airflow, filter bowing, and air bypass. Dynamic Filtration Ltd., a major industrial filter and custom filter manufacturer in Waterloo, Ontario, explores these issues and their proper solutions in this blog.

 

How To Troubleshoot Malfunctioning Pleated Air Filters?

 

Clogged And Dirty Filters

 

Signs of a dirty and clogged industrial filter include reduced airflow, presence of dust in the environment and increased energy consumption. Some filter systems also have a visual check filter light that might turn on. In this case, the best solution is to remove the clogged pleated air filter and replace it with a new one. Of course, proper filtration efficiency and size have to be considered.

 

Reduced Airflow

 

Sometimes, the pleated air filter might see a reduction in airflow even without the presence of clear dust buildup. However, it still signifies clogging in the industrial filter. To prevent this problem, keep inspecting the pleated air filter every three months and replace it promptly if required.

 

Filter Bowing

 

A bowed industrial pleated air filter signifies that the filter is severely clogged, causing the bowing or bending. This requires immediate replacement, as a bowed industrial filter will allow contaminated air to bypass through the filter, leading to a marked reduction in air quality.

 

Air Bypass

 

If the filter is performing properly, but the air quality is still low, then air bypass might be the cause. Common reasons include an improperly fitted or small pleated air filter. To counteract this, make sure that the pleated air filter fits snugly into the housing.

 

Conclusion

 

To conclude, signs of a poorly functioning pleated air filter include clogged filters, reduced airflow, bowed filter and air bypass.
